    Heavy electrons: new ways to break old rules

    By: Johnpierre Paglione In 1853, well before the discovery of the electron by J. J. Thomson in 1897, two German physicists named Gustav Wiedemann and Rudolf Franz made the peculiar observation that the ratio of electrical to thermal conductivities is the same in several different Read More

    Sudden Breakups of Monogamous Quantum Couples Surprise Researchers

    Quantum particles have a social life, of a sort. They interact and form relationships with each other, and one of the most important features of a quantum particle is whether it is an introvert—a fermion—or an extrovert—a boson. Extroverted bosons are happy to crowd Read More

    When Superfluids Collide, Physicists Find a Mix of Old and New

    Physics is often about recognizing patterns, sometimes repeated across vastly different scales. For instance, moons orbit planets in the same way planets orbit stars, which in turn orbit the center of a galaxy. When researchers first studied the structure of atoms, they were tempted Read More

    Researchers Identify Groovy Way to Beat Diffraction Limit

    Physics is full of pesky limits. There are speed limits, like the speed of light. There are limits on how much matter and energy can be crammed into a region of space before it collapses into a black hole. There are even limits on Read More

    Researchers Imagine Novel Quantum Foundations for Gravity

    Questioning assumptions and imagining new explanations for familiar phenomena are often necessary steps on the way to scientific progress. For example, humanity’s understanding of gravity has been overturned multiple times. For ages, people assumed heavier objects always fall quicker than lighter objects. Eventually, Galileo Read More

Chancellor Emeritus John S. Toll Passes Away at 87

On Friday, July 15, the University of Maryland lost John S. Toll, one of its most prized and influential figures. Dr. Toll was a physicist, scholar and educator whose many achievements included the development of Maryland physics from a small department to one of the largest and finest in the nation.

After serving in the Navy during WWII, Toll completed his Ph.D. in physics at Princeton. In 1953, he became chair of UMD's Department of Physics and Astronomy. He left in 1965 to serve a remarkable term as president of SUNY Stony Brook, then returned to UMD in 1978 as president and later Chancellor of the University of Maryland system.

In physics, he is well known for his work in developing the modern approach to dispersion theory and its application to problems in elementary particle physics.

In 2002, the Maryland physics building was named in his honor.
